Impressive, you really love pi, don't you

Sorry im just a noob

ha ha ha, I'm so glad I answered

No it equal annoying brothers :)

a blood brother or bro time

If you don't know how to work any of them.....you should probably work all of them...or, at least, as many as you can.....

Everybody knows dumdum

I Like to say that it is what you think math is.

It's 19 and 21

the answer is 10 to the 10000 power

y = 3x^2 + 24x + 43    factor out the 3

y =3 (x^2 + 8x + 43/3)    complete the square

y = 3( x^2 +8x + 16 + 43/3 - 16)    factor the first three terms

y = 3[ (x + 4)^2 - 5/3 ]     distribute the 3 back

y = 3(x + 4)^2 - 5

The coordinate of the vertex is (-4, -5)  

The x intercepts are about (-5.291, 0) and (-2.709, 0)

The y intercept is at (0,43)

The line of symmetry is x = -4

Here's the graph.......notice that both equations are exactly the same graph.....

I can give you my email and i can help youm study !

Thanks, these are great ideas! CPhill- what if I don't really know how to work any of them... (I'm really bad at math!) how should I study?

It's both 19 and 21 but the funny part is 21

I second that

No, but you can join everyone is welcome

You can ask for help !

Thank you so much! - you are a lifesaver! 

I have also some other complex numbers I need to find modulus and argument for.

• (1+√3i)(1-√3i)
  • z = a+bi = 1-√3i+√3i+3 = 4
  • lzl  = √(a^2 + b^2) = √4^2 = √16 = 4
  • arg(z) = tan-1(b/a) = tan-1(0/4) = 0 degrees
• conjugate -i
  • conjugate -i = i
  • lzl  = √(a^2 + b^2) = √1^2 = √1 = 1
  • arg(z) =  tan-1(b/a) = tan-1(1/0) = 90 degrees
• 1-i/1-i
  • z = a+bi = 1-i/1-i = (1-i)*(1+i)/(1-i)*(1+i) = 1+i-i-i^2/1+i-i-i^2 = 1+i-i+1/1+i-i+1 = 2/2 = 1
  • lzl  = √(a^2 + b^2) = √1^2  = √1 = 1
  • arg(z) =  tan-1(b/a) = tan-1(1/0) = 90 degrees

Is the calculations I did correct? - I think that the last one is wrong, but I just cant figure out why ..

Thanks, noob123......that's a good tip.....

No Problem

.5 inches 

-22 is correct...proof....

6 - 2(-22)  = 50

6 + 44= 50

50 = 50

4+4=8

2*3=6

3*2=6

1/6+1/6=2/6=1/3

answer: 8 1/3
